如何使用go编程语言在给定ip地址的情况下在网络上查找主机名
问题描述：
Using go programming language, I'm able to find the IP address given the host name, but what I'm looking for is to find the host name given the ip address. I tried researching the "net" package, but no luck.
Is this something possible in golang? please advice.

答
LookupAddr should do what you are looking for:
LookupAddr performs a reverse lookup for the given address, returning a list of names mapping to that address.
